Efficient enzymatic syntheses of isosteric phosphono analogues of sugar nucleotides have been accomplished using a thymidylyltransferase.

Abstract. Based on source-specific saccharide tracers, the characteristics of biomass burning (BB) and biogenic emissions saccharides were investigated in three rural sites at Lincang, which is 65 % covered with forest southwest border China. The total accounted for 8.4 ± 2.7 organic carbon (OC) 1.6 0.6 PM2.5. measured anhydrosugars 48.5 saccharides, among levoglucosan was most dominant species...

Conversion of agricultural residues into valuable products has become an important study in the industry. Generally, they are made up lignocellulose biomass which requires a particular method such as pretreatment to enhance desired yield produce end product. However, pumpkin is commercialized very little way Malaysia, and their processing generates tons seeds peels byproducts. Not mention fact ...

Swimming is a healthful activity that comes with increased risk of exposure to pathogenic microorganisms and disinfection agents/byproducts.

Several ionic liquids were applied as catalysts for the synthesis of cyclic urethanes from amino alcohols and pressurized CO2 in the presence of alkali metal compounds as promoters. A comparative study was made for the catalytic performance using different ionic liquids, substrates, promoters, and pressures. The optimum catalytic system was BMIM-Br promoted by K2CO3, which, for 1-amino-2-propan...

Abstract Background Pretreatment is the key step for utilizing lignocellulosic biomass, which can extract cellulose from lignin and disrupt its recalcitrant crystalline structure to allow much more effective enzymatic hydrolysis; organic acids pretreatment with dual benefic generating xylooligosaccharides boosting hydrolysis has been widely used in adding values lignocellulose materials. In thi...

Coal and coal combustion byproducts can have significant concentrations of lanthanides (rare earth elements). Rare earths are vital in the production of modern electronics and optics, among other uses. Enrichment in coals may have been a function of a number of processes, with contributions from volcanic ash falls being among the most significant mechanisms. In this paper, we discuss some of th...
